To all whom 'it may concern:

Be it known that I, WITMER J. Knnme, a citizen of the United States, residing atLancaster. in the county of'Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Razors,

of 'which the following is a. specification,

reference being bad therein panying drawing. r

Mv invention relates to safety-razors, and more particularly to that class which are provided with a razor-blade having a continuous cutting edge and also which is of such a construction that the razor can be moved upon any part of the skin in any direction, and in this way a much greater cutting edge is available than in any straight edged razor, as the blade being circular in form, one-half of its cutting edge is in use at the sametime. i

Another object of my invention is to provide a novel construction of safety-razor andirazor-blade therefor, which is simple of construction, contains few parts, is easily cleaned and may behoned without disassembling (which .is a feature embodied in no other safety-razor) and which, owing to its to, the accomcircular form, which may be very small, it

may be used to greater advantage than other, razors and still have a large cutting. edge.

While I am aware that there have been safety-razors constructed having a circular blade, they are all made with an ap roximately flat blade, or with a blade whic 1 presents a convex surface to the face, or which has a convex cap that tends to force the blade away from the face: and forms a wrong cutting angle with the face, and in this connection it may be stated that it is awell known fact that the best cutting razors are those which present a concave surface to the face, and this I have accomplished in my device,as I employ a circular concavo-con-' vex blade which is retained in the holder with the concave side next to the face at the proper angle to present the finest cutting edge.

I required. I A further object of the inventlon is to pro- Another object of the invention is that as the blade is only sharpened upon the concave side, the blade may be honed while in the holder and thus no stroppinndevice is vide a safetymazor =of sucha construction that the frame or holder affords a receptacle or receiver in which the,lather is collected duringthe act of shavingfand which may be cleaned by holding it under a faucet, as there are no -inclosed parts necessitating taking the razor apart to clean.-

'Still another object of my device is that by employing a circular concavo-convex blade a shearing cut or stroke is obtained while drawing the razor upon the skin. I With these and other objects in view my inventlon conslsts in certain constructlon and combination of parts as will hereinafter be fully described and claimed in theannexed specification and illustrated in the accompanying drawings which form a part of this application, and in which like figures of reference refer tocorresponding parts in all of the views; but it is fully understood that while I have described my invention as herewith shown, that I do not-confine myself to the exact design as shown, as slight changes may be made in the construction and combination of parts without departing from the spirit of the invention.

In the drawings :Figure 1, is a transverse vertical sectional view of the assembled device. Fig. 2, is a to plan view of the same, showing the guard concave top. Fig. 8, is'a side elevation of the guard-case. Fig. 4, is atransverse vertical sectional view of the blade. Fig. 5, is a plan view of the concave side of the blade, showing the ground surface or cutting ring.

Fig. 6, 1s a transverse vertical sectional view I the reception of the cap stud 11.

The guard-case which is of an inverted cup shape is formed with the top 3, of concavo-convex form, and its edge is cut away to formthe c'ombteeth l; whilethe center of said'top' is providedwith the orifice 5.

p The blade 6, is here shown as composed of an even thickness of steel, conca'vo-convex in form, except where it is ground, fiat 7, near the edge on the concave side to form the cutting edge 8, and the blade is further provided with the central orifice 9.

The cap 10, constituting the fourth and last member of the device is of a circular concavo-convex form of slightly less diamcomb and its.

eter than the blade and is formed with the screw-threaded stud 11, de ending from the center of the convex side t ereof.

To assemble the device the blade 6, is placed with its concave side next to the cap 10, the stud 11 extending through the onfice in the blade; the guard is next placed upon the stud 11, with its concave surface in contact with the convex surface of the blade 6, and the handle 1, is now screwed upon the stud 11, thus securing all of the members in place, and the device is now read for-use.

hen it is desired to hone the razor, this may be done without takin out the blade,

as it will be seen that by p acing the razor concave side down upon the hone and giving it a circular rubbing motion that the ground surface or ring 7 is brought into the proper contact with the hone, and thus no special stropping device is required as is the case with all other safety-razors.

Having thus described my invention what I claim as new anddesire to secure by Letters Patent is 1. A safety-razor com rising an inverted cup-shaped guard or ho der formed with a concave upper surface and provided with a central orifice, a concave-convex circular blade formed with a central orifice 1n the body thereof, a clrcular concave-convex cap provided with a screw-threaded stud depending from the convex side thereof and passing through the central orifices in said fice in the bod guard and said blade, and a tubular handle adapted to.be screwed thereon with its end in contact with said guard.

2. A safety-razor comprising a circular concavo-convex holder formed with an orithereof, a circular concavoconvex blade ormed with an orifice in the body thereof and placed with its convex side in, contact with the concave side of said holder, a circular concavo-convex cap formed with a depending stud from the convex sur- 'face thereof and placed with its convex surface in contact with the concave surface of said blade and with its dependin stud extendinithrough the orifices in said fielder and said lade, and a handle screw-threaded upon said stud below said holder and retaining all ofsaid members in place.

3. In a safety razor, a guard plate concave-convex in cross-section and having a curved periphery provided with teeth, a blade concavo-convex in cross-section and having a cutting edge cooperating with the said guard teeth, and a cap plate concaveconvex in cross-section, together with means for rigidly holding the blade between the cap plate and the guard late.

In testimon whereof afiix my signature in presence 0 two witnesses.
